Does anyone know of an actual case of a person who was impacted by this? What difference does that make? It's wrong, regardless of whether or not one can cite

Does anyone know of an actual case of a person who was impacted by this? What difference does that make? It's wrong, regardless of whether or not one can cite a specific case where it affected someone. This is no different than the b.s. "you don't need privacy if you don't have anything to hide" crap that people spout sometimes. If the govt. needs this information, the can get a warrant. If they can't get a warrant, they don't need the information. This isn't that hard to figure out.
